Never use a cheater pipe extension on the hydraulic pump handle. Failure to comply may result in personal injury.
7.Make sure the release valve is closed, then use the pump handle bar (Figure 7) to advance the die and bend the pipe.

8.When you are finished with your bend, release the pressure by opening the release valve and the ram will automatically retreat.
Operation tips and tricks:
•If the ram reaches the end of its stroke but still has not completed a desired bend, release pressure just enough to remove the pipe. Set the rollers either one or two holes farther in to finish the bend.
•We recommend making templates of accu- rate 45˚ and 90˚ angles. Compare these templates to an almost finished pipe so you do not over- or
•If you pass the 45˚ angle mistakenly, you can sometimes reverse the pipe and slightly press it enough to reach the required 45˚.
•Bending any angle may thin and stress the walls and narrow the center of the pipe. If you need to make bends more than 100˚, we recommend heating the pipe during bending. Generally, heat weakens metal, but it will allow it to bend more freely.
•Pipes bent past 90˚ will flow into the bending die, making the pipe hard to remove after bending. Greasing the inside of the die will make this removal easier, or switching to a larger die for bending the last few degrees will eliminate this difficulty.
MAINTENANCE
•The Model G9017 and G9018 are basi- cally maintenance free. However, the oil level should be kept constant at about 2.5 pints of quality hydraulic oil.
•Too much oil will force the surplus oil to leak from the bottle jack fill plug (Figure 8), caus- ing a mess.
•Not enough oil will cause loss of power.
To add oil:
1.Set the tube bender upright, retract the piston rod fully and remove the fill plug (Figure 8).

2.Fill the bottle jack to the level of the fill plug hole and replace the fill plug.
3.Place the tube bender in its operating posi- tion, fully extend the piston rod, then retract the rod to expel air in the bottle jack.
4.Remove the fill plug and repeat Steps 2 & 3 until all of the air is expelled.
